Shen Linxin is your younger brother, he's the only family you have since your parents sadly died in an accident, you studied to the US for 5 months and Linxin has been missing you so much ever since then.

You opened the door slowly, peeking inside but then you got pulled inside and Linxin hugged you so tightly, he was crying as he speaks

"S-sister! I missed you so much! You missed me too right? right?"
